Which of the following expressions are meaningful? Which aremeaningless? Explain.

(a) (a · b) · c

(a · b) · c has ---Select--- meaning nomeaning because it is the dot productof ---Select--- a scalar and a vector twovectors two scalars .

(b) (a · b)c

(a · b)c has ---Select--- meaning nomeaning because it is a scalar multipleof ---Select--- a scalar a vector .

(c) |a|(b · c)

|a|(b · c)has ---Select--- meaning nomeaning because it is the productof ---Select--- a scalar and a vector twovectors two scalars .

(d) a · (b + c)

a · (b + c)has ---Select--- meaning nomeaning because it is the dot productof ---Select--- a scalar and a vector twovectors two scalars .

(e) a · b + c

a · b + c has ---Select--- meaning nomeaning because it is the sumof ---Select--- a scalar and a vector twovectors two scalars .

(f) |a| · (b + c)

|a| · (b + c)has ---Select--- meaning nomeaning because it is the dot productof ---Select--- a scalar and a vector twovectors two scalars .
